COMPOSITION FOR ROOFING, PAVING, 8M2.

SPECIFICATION forming part of letters Patent NQ 617,706, dated January 17. 18 9..

than mu uecembar 24. 1896.

To all whom it may oncern-.-

lie it known that I, Cuxnnss E. Axruoxv, a citizen of the United States of America, rcsiding at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Couiposition for Rooting, Paving, &e.; and I do declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same.

This invention is a composition of matter for use in the manufact u re of rooting, paving, sheathing, floor-coverings, house-linings, and other articles.

One of the ingredients of the composition is itself a new product of my invention and is made the subject of a separate application. This product is produced byheatinfr wurtzih he to; predetermined high temperaturesay 600 Fahrenheit-i n a closed retort, where by it is rendered soluble and fusible, whereas the crude material does not possess such properties. his wnrtzilite product may be said to form. the base of the present composition of matter, whose other essential ingredients are asphaltnm and maltha or their equivalents. A good commercial composition is need by combining these ingr cuts in the following proportions: wurtzil e, two hundred pounds; asphaltum, fifty pounds; maltha, ten pounds. These ingredients are dissolved eitherscparatelyor in combination.

The wurtzilite product is fusible and soluble by any solvent-such as gnsulene, naphtha, turpentine, tier-and the other ingredients are added to it and the whole mass thor onghly incorporated and reduced to a liquid state. The mixture is then read y for use. Its uses are various, and among the principal are the following:

First. Roofing or sheathing felt, due: The liquid mixture is spread by hand or machinery in the ordinary method of waterproofing or overlaying upon asnitablc flexible hacking-such as burlap, canvas, muslin, or other fabric or felt. After the mixture has been applied to such backing powdered mica is dusted or spread upon the surface thereof and the sheets thus prepared passed through rolls, so that the mica may be pressed onto the material to give a linish to the exterior Serial F0 816.936. elk Ipecimens.)

surface thereof. The mica increases the durability of the article. This forms a superior material for roofing, sheathing, the, as the composition will withstand a very high degree of heat and is nnafiected by the heat of the sun. It is, moreover, very durable and is pliable in all kinds of weather.

Second. Paving: To use the composition for making pavements and the like it is mixed with sand, gravel, pulverized stone, or like material, as in ordinary common paving mixtures,the composition rendering the pave meut waterproof, durable, and unafiected by ordinary temperatures or by the heat of the sun, and by reason of the elasticity of the composition it will not crack.

These are but two of the many uses to which the composition may be applied.

The above-steted-prepcrtions of ingredi cuts of the composition may be varied according to the climate in which it is to be used. In warm climates more wurtzilitc should be used than in-cold climates.

As an equivalent-of asphaltum in said composition, other bitnmens, such as gilsonite, might be used.

As an equivalent of maltha, I can use residuumfrom petroleum-oils,crudepetroleum, liquid asphalt, or some oLthe n'on-drying vegetable oils, such as cotton-seed oil, linseed- Oll, LEO- In the place of and as an equivalent for mica I may apply powdered soap or talc, sand, asbestos, or any other suitable material.

lla ving thus fully described my invt ition. what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. As a new composition of matter, the described wurtzilite product, together with asphaltum and maltha, all combined substantially as described.

:3. The herein-described compositlf-n ol. matter consisting of two hundred parts of the specified wurtzilito product, fifty partsof asphaltnm, and ten parts of maltha, substantiallyas and for the pn described.

In testimony whereof ulfix my signature in presence of two witnesses.
